IVALTER J. TIDD, OF SPRINGFIELD, MASSACHUSETTS, ASSIGNOR T0 TIDD RECORDING CLOCK COMPANY, OF SPRINGrIEHJLD,v MASSACHUSETTS, A CORPORATION OF MASSA- CHUSETTS.

TIME-RECORDER.

- v Specication of Letters Patent.

To all whom it may concern Be it known that I, WALTER J. TIDD, a citizen of the United States, and residing in Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Time-Recorders, of which the. following is a specification.

This invention relates to improvements in time recorders and is designed to be used for indicating the time that a watchman or other person having the care of property makes the usual rounds or beats. The invention is designed to be placed on the inside of a store door and operable from the outside. The invention broadly comprises a clock mechanism which is mounted Within a suitable casing that is closed at one end, the open or opposite end being turned toward the door and designed to be readily attached to a plate that is designed to be readily removed from the inside of a door or other fixed support of the building. A dial bearing numbers indicatin the hours of the day is fixedly secured to t e framework of the movement. A perforating device is carried by the rotatable hour post of the clock, suitable means being provided which is operable from the outside of the door, to move the perforating device into contact with the fixed dial for indicating the time that the watchman made his regular inspection tour.

Referring to the drawings:

Figure 1 is a vertical sectional view through the axis of the clock movement and its casing, also through the axis of the spring actuated perforating device, showing the general construction and arrangement of the parts.

Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1 looking toward the inside of the clock, showing the perforatable dial;

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1 looking toward the left and illustrating the ring member which actuates the perforating device also disclosing the method of attaching the plate which secures the movement to the door;

Fig. 4 is an enlarged sectional detail view of the perforating device that is carried by the hour post of the clock, the perforating arm of said device being shown away from the fixed recording dial;

Fig. 5 is an enlarged sectional detail view on the line 5 5 of Fig. 2 showing the manner of attaching the perforating arm to the hour post of the movement.

Referring to the drawings in detail: 1 designates the door or other support to which the clock casing 2 is pivotally attached, by means of the hinge construction indicated at 3. 4 is a plate that is secured to the door by Patented July 1, 1919. y

means of the screws 5 which pass through L the enlarged openings 6 therein. The clock train or movement as a whole is` indicated by the numeral 7 which'shows the usual hand setting button and the usual Winding key 8 on therear side of the casing. The hour post is indicated at 9. 10 indicates a time recording disk or dial preferably of paper which is temporarily secured to and positioned on a fixed plate 11 by means of the pins 12. Spaced from the plate 11 is a flat ring 13 which is secured to the plate 11 by means of the curved connecting strips 14. The annular space or opening 15 between the plate 11 and ring 13 permits the dial perforating pin 15 on the end of the spring arm 16 to pass through the time recording paper dial when it is forced inward toward the clock movement.

The spring arm 16 is fixedly secured to an arm 17 by means of a hollow rivet 18 which fits onto the hour-post. A pivoted latch 19 is pivotally attached to the spring arm 16 for securing the spring arm 16 and its supporting arm 17 to the hour post. The hooked shaped end of this latch lits into a recess 20 in the hour post (see Fig. 5).

The arm 17 is prevented from turning or slipping on the post -9-- by means of the slot and rib construction 21 and which also serves to accurately position the perforating arm on the hour post.

In order to force the perforating arm inward toward the fixed time recording disk of paper 10, a ring shaped member 22 is attached to the inner end of a slidable rod 23, which ring whenwactuated by the watchman from the outside of the door by pushing inward on the knob 24 will engage the spring arm 16 at any part of its travel and force the sharp point 15 through the time recording disk of paper 10, producing a perforation on the circle containing the figures which indicate the hours of the day as shown.

The rod 23 is normally forced outward by means of the coil spring 24 which isr located within a cylindrical shaped casing 25, one

end bearing against the bottom of the casing and the other against a Washer or collar 25, secured to the push rod 23, whereby the rod and ring 22 is normally retracted away from the spring arm 16.

The ring 22 may be rod 23 in any suitable Way or by means of the threaded extension 26 having a ring securing nut on its inner end as shown.

It ivill be seen from this construction that the disk of paper which records the time may be readily inserted in and removed from the clock movement by simply unlatching the casing at its top by releasing the spring latch 27 and lowering the casing into the dotted line position 2.

In order to prevent the disk of paper from being detached from the positioning pins 12, a collar 28 is provided on the hub 18.

lVhat I claim is:

l. A ivatchmans time recorder comprising in combination with a suitable inclosing casing having an open end, a clock movement therein. the open end of said casing being pivotally secured to the inside of a door or other support, means for holding the casing in a closed position, said movement having a plate fixed to the frame ivork of the movement, a time recording disk temporarily secured to the fixed plate by means of pins on the fixed plate, means for perforating the disk comprising a pin on a spring arm and an arm to which the spring arm is attached by means of a hollow rivet carried by the hour-post of the movement and a ring operable from the outside of the secured to the push door, or other support, for engaging the spring arm at any point in its path of rotation for forcing the pin against the disk for perforating the same.

A Watchmans time recorder comprising in combination, an inclosing casing, a clock movement therein, a disk secured against movement and bearing numerals to indicate time, a spring-arm, carried by the hour post of the movement and having a porforating pin, an arm to which the spring arm is attached and also attached to the hour post, means for attaching the tivo arms to the hour post, comprising a hollow rivet and a latch secured to the Spring arm, a member located on the inside of the door for engaging the spring arm in any position, said member being operable from the outside of the door.

3. A watchmans time recorder comprising in combination an inclosing casing open at one end and having its open end turned toward the inside of a door or other support,

means for pivotally securing the open lower end of the casing to the door, a clock movement in the casing, a recording disk, a detachable spring arm having a perforating pin thereon carried by the hour post for perforating the disk, inea-ns for engaging 1 the spring arm in any part of its path for forcing the pin through the paper, `land means on the arm to prevent the disk from being displaced when the perforating pin is retracted.
